$\huge\sf\color{purple}{Loudness Of Sound :-}$

• Loudness is defined as the property of sound which is used for differentiating between the loud and faint sound.

• Loudness is dependent on the energy received by the ear in unit time.

• Loudness is independent of the change in frequency.

$\huge\sf\color{purple}{Pitch Of Sound :-}$

• Pitch is defined as the characteristic of sound which is used for differentiating between the shrill and flat sound

• Pitch is independent of the energy received by the ear in unit time

• Pitch is dependent on the change in the frequency. As the frequency increases, the shrillness of the sound increases

========================

$\huge\sf\color{purple}{Persistence Of Hearing :-}$

Persistence of hearing of a human ear means how much time the sensation of any sound stay in our brain. For normal human ear the value is 0.1 s. Now If the persistence of hearing is increased or decreased compared to normal ear ,it indicates the hearing loss of the human ear.
